Fixed to return the checksum status of rx packets by setting
"ol_flags" correctly in vector mode receive.
These changes have been there for non vector mode receive.
In vector mode receive also indicate inner and outer checksum
errors individually in "ol_flag" to indicate L3 and L4 error.
Fixes: bc4a000f2f53 ("net/bnxt: implement SSE vector mode")
